Rate Schedules & Tariff Analysis
SMECO C&I rates layer a fixed customer charge, tariff-set base energy and (for medium-and-up classes) base demand charges, a monthly Power Cost Adjustment, and a Bill Stabilization Adjustment. As an SOS provider in a deregulated market, the generation/supply component is reflected in the Price to Compare, which customers can replace with a competitive supplier. Demand charges ($/kW) dominate cost for low-load-factor facilities, making load-factor and TOU management the primary levers.

Southern Maryland Electric Cooperative (SMECO) Data Access FAQ
Can a C&I customer get 15-minute interval data from SMECO?▾
Yes. SMECO's AMI smart meters record 15-minute intervals. Commercial accounts can view hourly/15-minute detail in Account Manager's Energy Use Details and export it as a Green Button CSV. There is no real-time API, so exports are manual.
How does a consultant or energy manager pull our usage data?▾
Two paths: (1) the customer downloads Green Button CSV / bill PDFs from Account Manager and shares them, or (2) the consultant submits an authorized historical-data request to SMECO Supplier Support with written customer authorization and receives an Excel/CSV file in 5-10 business days. SMECO has no Connect My Data API.
Which rate schedule applies to our facility?▾
SMECO classifies non-residential load as General Service Small (GSS), General Service Medium (GSM), General Service Large (GSL), Large Power (LP), or Transmission Service (T), generally by demand level. Medium and larger schedules are demand-metered (kW) with separate energy (kWh) charges. Each schedule has SOS and Time-of-Use (TOU) variants.
Can we shop for a competitive electricity supplier?▾
Yes. Maryland is deregulated for generation supply. SMECO members can buy supply from a licensed competitive supplier while SMECO delivers the power. Compare offers to SMECO's monthly Price to Compare (May 2026 SOS: $0.134827/kWh).
Does SMECO offer Time-of-Use rates for businesses?▾
Yes. Each commercial schedule (GSS, GSM, GSL, LP, T) has a TOU variant in the published tariff. TOU can lower costs for facilities that can shift load away from on-peak periods; use Account Manager's rate comparison tool to model the impact.
Are demand charges part of the SMECO bill?▾
Yes, for medium and larger commercial classes. The May 2026 Power Cost Adjustment includes demand components (for example, $0.82/kW for GS Medium and $0.78/kW for GS Large), and the underlying tariff schedules set base demand charges in addition to energy ($/kWh).
